SUBMARINE OR SUBMERGIBLE BOAT.

Specification of Letters Patent.

Application filed March 13, 1311.

Serial No. 614,115.

To all whom it may concern:

Be itknown that I, EDWARD LAsIUs PEA- ooox, a subject of the King of Great Britain, at present residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Submarine or Submergible Boats, of which the following is a specification.

The object of the invention is to provide the deck of submarine or submergible boats with one or more adjustable sections that are capable of being adjusted vertically out of alinement with the deck so as to present inclined surfaces or planes to the passing water when the beat is under way to cause the boat to rise and sink as with the use of the horizontal rudders and hydroplanes now employed for this purpose on this class of boats, thereby dispensing with said rudders and hydroplanes and their connections and all external speed resisting surfaces and providing a smooth even hull whereby the speed of the boat may be increased with a relative amount of motive power, said sections being also adapted to provide greater freeboard when the boat is operating on the surface.

To this end the invention consists in cer- I Figure 1 is a diagrammatic side elevation of a submarine torpedo boat embodying my improvements. Flg. 2 1s a slmllar vlew 1n plan. Flg. 3 1s a diagrammatic sectional elevation of the amidships section and the after end of the boat. Fig. 4 is a similar view of the forward end of the boat. Fig. 5 is a horizontal section drawn on the line 55 of Fig. 4, looking in the direction indi cated by the arrows. Fig. 6 is a transverse section on a larger scale drawn on the line 66 of Fig. 1. Fig. 7 is a side elevation of one end of the boat illustrating a slightly different form of adjustable sections.

1 designates the body or hull of a submarine torpedo boat having upon its top a superstructure 2 that is connected to the hull 1 in the usual manner. As shown, the superstructure extends throughout the length of the hull, although it may be arranged only at the amidships section of the boat if desired and is constructed of sides 3 and a deck 4.

5 designates supporting arches or ribs for the superstructure.

6 designates the conning tower of the boat which extends upwardly from the hull 1 through the superstructure 2.

The sides 3 of the superstructure are preferably parallel throughout their major length with converging ends that terminate in sharp vertical edges to form a water cutting edge at the bow and to avoid the forma tion of dead water at the stern of the boat when the boat is under way thus tending to lessen the resistance to the speed of the boat. The ends of the deck 1 terminate some distance from the ends of the sides 3 as at 4 and the sides 3 are cut away from the ends 1" of the deck in downwardly inclined directions toward the ends of the boat as at 7, and j ournaled in suitable bearings 8 secured to the sides 3 adjacent to the ends a of the deck are adjustable deck sections 9 that form continuations of the deck 4: and which are of tapering form in plan to conform to the converging sides or ends of the superstructure. To the longitudinal edges of the deck sections 9 are connected side portions 10 that extend the full length of said deck sections to form continuations of the sides 3 when the deck sections 9 are arranged in longitudinal alinement with the deck 4 or have their free ends elevated above the deck thereby closing the openings formed by the cut away sections of the ends of the sides 3 to prevent the ingress of great quantities of water when the boat is running on the surface especially in rough weather and also to present an even unbroken surface to the sides when the boat is running submerged. The lower edges of the sides 10 converge toward the deck sections 9 from their outer ends toward their inner ends. The deck sections 9 and their sides 10 are braced by suitable ribs or arches 11 and if desired each may be provided with a central longitudinal rib 12 extending the full length of said sections.

To the undersides of the deck sections 9, intermediate their ends, are pivotally con nected links 13 to the lower ends of which are connected vertically movable shafts 14 that extend downwardly through the skin or plating of the hull 1 and through stuffing boxes surrounding the openings in the hull through which the shafts pass. The lower ends of the shafts 14: are threaded as at 15 to operate in threaded hubs 16 of hand operating wheels 16 revolubly held in brackets 17 arranged within the hull of the boat. parent that by revolving the wheels in one direction 7 or the other the adjustable sections 9 will be correspondingly raised or lowered. As shown in the drawings the links 13 are pivotally connected to the longitudinal ribs 12 of the deck sections 9 but it will be understood that they may be connected to other portions of said sections and if desired the sections may be formed with or connected by lever arms extending from the pintle ends thereof and the links 13 or the shafts 14: connected to said arms.

At amidships the deck is formed with an opening 18, substantially cone-shape in horizontal section, which surrounds the conning-tower 6 with the widest part of the opening arranged forward of the conningtower and its point arranged aft of the rear end of said tower, and at the forward end of the opening is journaled the forward end of an amidships adjustable deck section 19 which is of a shape to snugly fit within the opening 18 and which is formed with an opening 20 through which the con ning-tower 6 passes. The pintle 21 of the section 19 is'held in brackets 22 secured to the upper inner ends of the sides 3 of the superstructure. To the longitudinal edges of the deck section 19 are connected down wardly extending sides 28 which are of gradually increasing depth from the pintle end toward the rear pointed end of the deck section 19. The purpose of constructing the amidships section of substantially cone-shape in horizontal sectionit will be i understood is also for the purpose of avoiding the formation of dead water at the after endof the section when it is elevated above the deck 4:.

A link 24 is pivoted to the underside of the section 19 adjacent to its rear end and to this link is connected the upper outer end of a vertically movable shaft 25 whose lower end is extended into the hull of the boat and through a stuffing box 26-surrounding the opening'in said hull and has its lower end formed with screw threads 27 which operate in threaded hubs 28 of a hand operating wheel 29 revolubly held in a bracket 30 mounted in the boat.

'31 designates bulk-heads arranged in the space formed by the superstructure and the hull'of the boat at the ends of the adjustable sections.

In order to indicate to those within the boat the degree of movement imparted to the adjustable deck sections, I provide the By this arrangement it will be ap-' inner ends of the shafts 14 and 25 with degree marks as at 32 which operate in conjunction with index pointers 33 held in any suitable manner adjacent the shafts whereby as the operating wheels are revolved in either direction the degree marks will be brought opposite the index pointers and thus indicate to the occupants of the boat the degree of movement imparted to the adjustable sections.

In operation, when it is desired to submerge the boat, water is first admitted into the ballast-tanks (not shown) of the boat in the usual manner until the deck of the boat is slightly below the surface of the water, the forward end of the adjustable bow deck section 9 is then lowered so that the plane of said section will lie at an angle to the deck 4 of the superstructure, while the rear ends of the stern deck section 9 and the amidships section 19 are elevated so that their planes will be correspondingly arranged at an angle to the deck 4;, then as the boat is propelled through the water the water will engage the inclined surfaces or planes and force the boat under the water in the same manner as is now done with the horizontal rudders and hydroplanes used in this class of boats. When the desired depth of submergencc has been reached and it is desired to remain at such depth, the adjustable sections are adjusted so as to decrease their degree of inclination and thus hold the boat on an even keel and at the desired depth. Now when it is desired to rise to the surface, the adjustable section 9 at the in alinement with the deck 4: so that as the boat is propelled the passing water will engage only the inclined plane 9 at the stern of the boat thus depressing the after end of the boat and elevating its forward end which will cause the boat to travel toward the surface as it is propelled through the water.

It will thus be seen that I provide an exceedingly simple and highly efiicient construction for accomplishing the purposes stated by which the horizontal submerging and trimming rudders and hydroplanes and their connections are dispensed with, which enables me to construct the hulls of this class of boats with the fine lines and with smooth surfaces that are essential to speed. It will also be understood that in providing the deck ofsuch boats with'my improved submerging and trimming planes that the latter may be adjusted so that their free ends will be elevated to provide greater freeboard when the boat is operating 011 the surface.

I desire it understood that I do not limit myself to the details of construction or to the location of the adjustable sections as shown and described as they may be changed in construction and location without departing from the scope ofthe invention.' For example, the sections may be arranged upon and connected direct to the upper surface or deck of the hull of the boat when able section may be arranged on the top off the conning-tower as effectively as in the deck of the superstructure or on the deck of the hull adjacent to or surrounding the conning-tower, and still further the sections may be operated hydraulically, electrically or by compressed .air instead of by the means shown. 1 i

In Fig. 7 I show one end of the boat with the adjustable section 9 journaled direct upon the deck or top of the hull 1 and in this construction also the adjustable section is shown as a balancing section, having a rearwardly extending portion 9 projecting beyond the pintle of the section and in this construction in order to permit the elevation of the outer end of the section 9 I provide the top or deck of the hull 1 witha recess 1 to receive the inwardly extending end 9* as will be readily understood.
